JPMorgan Chase, a banking giant, has crossed new boundaries by settling a transaction involving tokenized Treasury bonds on a public blockchain, moving beyond its private blockchain network. This groundbreaking move was made possible with the assistance of crypto firms Chainlink and Ondo Finance.
JPMorgan Chase, a major player in traditional finance, has long been exploring blockchain technology primarily within its own private ecosystem, often referred to as a “walled garden.” However, the American bank has just announced a significant milestone: settling its first transaction on a public ledger through a strategic collaboration with specialized companies Chainlink (LINK) and Ondo Finance (ONDO).
In early May 2025, Kinexys, JPMorgan’s blockchain division, facilitated a fund transfer between two accounts on its private network. The goal was to settle the purchase of tokenized U.S. Treasury bonds offered by Ondo Finance and recorded on a public blockchain. To ensure secure communication and trigger payment between these two distinct environments (private and public), JPMorgan utilized the Chainlink oracle protocol.
This operation highlights Chainlink’s crucial role in facilitating cross-chain transactions and connecting traditional financial systems to new blockchain-based infrastructures. Ondo Finance, on the other hand, positions itself as a key player in providing tokenized Real-World Assets (RWAs), specifically market products backed by Treasury bonds.
While JPMorgan has conducted several “proofs of concept” (POCs) in the past, this transaction is seen as a significant structural advancement. Nelli Zaltsman, Head of Platform Settlement Solutions at Kinexys, emphasized that it was the first time the bank had set up an architecture to interact in this manner with a public blockchain.
Sergey Nazarov, co-founder of Chainlink, echoed this sentiment, stating that “this is not just another POC; this is the beginning of something big,” adding that the developed structure is on track for “production,” meaning broader usage.
This initiative is part of a broader trend where major financial institutions actively explore the tokenization of traditional assets to enhance efficiency, liquidity, and market accessibility. It also demonstrates an increasing recognition of the need for interoperability between existing systems and new public blockchain technologies.
According to JPMorgan, this advancement has been part of its strategic roadmap for several years and is not merely a reaction to recent cryptocurrency market fluctuations or regulatory landscape changes. It signifies a long-term commitment to exploring and integrating blockchain technologies.
The implications of this first public blockchain transaction are potentially vast:
This collaboration between JPMorgan, Chainlink, and Ondo Finance is more than just a technical experiment. It represents a significant step towards the convergence of traditional finance and decentralized finance worlds, with the promise of a more connected, efficient, and accessible global financial system.
